For a finite nonempty set $A$ of positive integers, $A =\{a_1, a_2,\dots , a_n\}$, we say the calamitous complement of A is the set of all positive integers $k$ for which there do not exist nonnegative integers $w_1, w_2, \dots , w_n$ with $k = a_1w_1 + a_2w_2 +\dots + a_nw_n.$ The calamitous complement of $A$ is denoted $cc(A)$. For example, $cc(\{5, 6, 9\}) = \{1, 2, 3, 4, 7, 8, 13\}$. 

Find all pairs of positive integers $a, b$ with $1 < a < b$ for which there exists a set $G$ satisfying all of the following properties:
1. $G$ is a set of at most three positive integers,

2. $cc(\{a, b\})$ and $cc(G)$ are both finite sets, and

3. $cc(G) = cc(\{a, b\})\cup \{m\}$ for some $m$ not in $cc(\{a, b\})$.
1. **Relatively Prime Condition**: 
   - For the set \( \{a, b\} \) to have a finite calamitous complement \( cc(\{a, b\}) \), \( a \) and \( b \) must be relatively prime. This is because if \( \gcd(a, b) \neq 1 \), then there exist infinitely many positive integers that cannot be expressed as \( a_1w_1 + a_2w_2 \) for nonnegative integers \( w_1 \) and \( w_2 \).

2. **Case \( a = 2 \)**:
   - If \( a = 2 \), then \( b \) must be odd (since \( \gcd(2, b) = 1 \)).
   - The set \( cc(\{2, b\}) \) will include all odd numbers less than \( b \).
   - We can construct \( G = \{2, b+2\} \). The set \( cc(\{2, b+2\}) \) will include all odd numbers less than \( b \) and \( b \) itself.
   - Therefore, for all integers \( n \ge 1 \), we have the solution \( \boxed{(a, b) = (2, 2n+1)} \).

3. **Case \( a = 3 \)**:
   - If \( a = 3 \), then \( b \) must not be a multiple of 3 (since \( \gcd(3, b) = 1 \)).
   - We can construct \( G = \{3, b+3, 2b\} \). The set \( cc(\{3, b+3, 2b\}) \) will include all numbers in \( cc(\{3, b\}) \) and the additional number \( b \).
   - Therefore, for all integers \( n \ge 1 \), we have the solutions \( \boxed{(a, b) = (3, 3n+1)} \) and \( \boxed{(a, b) = (3, 3n+2)} \).

4. **Case \( a > 3 \)**:
   - If \( a > 3 \), then all positive integers less than \( a \) but not \( a \) are in \( cc(\{a, b\}) \).
   - Let \( c \) be the smallest integer in \( G \). Since \( c \) is not in \( cc(G) \), \( c \ge a \).
   - **Case 1: \( c = a \)**:
     - We claim that \( cc(G) \) encompasses \( cc(\{a, b\}) \) and the additional integer \( b \).
     - If \( b \) is not in \( cc(G) \), then since \( a \) is in \( G \), any integer not in \( cc(\{a, b\}) \) is also not in \( cc(G) \), leading to a contradiction.
     - Therefore, besides \( b \), any integer not in \( cc(\{a, b\}) \) is not in \( cc(G) \).
   - **Case 2: \( c > a \)**:
     - Then \( cc(G) \) encompasses \( cc(\{a, b\}) \) and the additional integer \( a \).
     - Since \( c \) is not in \( cc(\{a, b\}) \), \( 2a \) and \( a+c \) must be elements of \( G \).
     - We also have \( c \le 2a \) since it is the minimal element.
     - **Subcase 2.1: \( c = 2a \)**:
       - The three integers in \( G \) are \( 2a, 3a, \) and some other integer \( e \).
       - Since \( b \) is not in \( cc(G) \), \( e = b - ka \) for some nonnegative integer \( k \).
       - If \( k \ne 0 \), then \( e \) is in \( cc(\{a, b\}) \), which is impossible. So \( e = b \).
       - But then \( a+b \) is in \( cc(G) \) but not in \( cc(\{a, b\}) \), leading to a contradiction.
     - **Subcase 2.2: \( b = c \ne 2a \)**:
       - The three integers in \( G \) are \( c, 2a, \) and \( a+c \).
       - Since \( 3a \) cannot be in \( cc(G) \), the only possibility is for \( c \mid 3a \), but then \( b \) and \( c \) aren't relatively prime, leading to a contradiction.

Therefore, the only families of solutions are \( \boxed{(a, b) = (2, 2n+1)} \), \( \boxed{(a, b) = (3, 3n+1)} \), and \( \boxed{(a, b) = (3, 3n+2)} \) for integers \( n \ge 1 \).
