1. **Identify pairs of integers that sum to a perfect square:**
   - We need to find pairs of integers from 1 to 16 such that their sum is a perfect square.
   - The perfect squares less than or equal to 32 (since \(16 + 16 = 32\)) are 1, 4, 9, 16, and 25.

2. **List pairs for each perfect square:**
   - **Sum = 1:** No pairs since both integers must be positive.
   - **Sum = 4:** \((1, 3)\)
   - **Sum = 9:** \((1, 8), (2, 7), (3, 6), (4, 5)\)
   - **Sum = 16:** \((1, 15), (2, 14), (3, 13), (4, 12), (5, 11), (6, 10), (7, 9)\)
   - **Sum = 25:** \((9, 16), (10, 15), (11, 14), (12, 13)\)

3. **Determine the placement of integers:**
   - **Start with 16:** Since 16 is only in the pair \((9, 16)\), 16 must be at one end.
   - **Next integer is 9:** Following 16, the next integer must be 9.
   - **Next integer is 7:** 9 is paired with 7.
   - **Next integer is 2:** 7 is paired with 2.
   - **Next integer is 14:** 2 is paired with 14.
   - **Next integer is 11:** 14 is paired with 11.
   - **Next integer is 5:** 11 is paired with 5.
   - **Next integer is 4:** 5 is paired with 4.
   - **Next integer is 12:** 4 is paired with 12.
   - **Next integer is 13:** 12 is paired with 13.
   - **Next integer is 3:** 13 is paired with 3.
   - **Next integer is 6:** 3 is paired with 6.
   - **Next integer is 10:** 6 is paired with 10.
   - **Next integer is 15:** 10 is paired with 15.
   - **Next integer is 1:** 15 is paired with 1.
   - **Last integer is 8:** 1 is paired with 8.

4. **Verify the sequence:**
   - The sequence is \(16, 9, 7, 2, 14, 11, 5, 4, 12, 13, 3, 6, 10, 15, 1, 8\).
   - Check each pair to ensure their sum is a perfect square:
     - \(16 + 9 = 25\)
     - \(9 + 7 = 16\)
     - \(7 + 2 = 9\)
     - \(2 + 14 = 16\)
     - \(14 + 11 = 25\)
     - \(11 + 5 = 16\)
     - \(5 + 4 = 9\)
     - \(4 + 12 = 16\)
     - \(12 + 13 = 25\)
     - \(13 + 3 = 16\)
     - \(3 + 6 = 9\)
     - \(6 + 10 = 16\)
     - \(10 + 15 = 25\)
     - \(15 + 1 = 16\)
     - \(1 + 8 = 9\)

5. **Consider the reverse sequence:**
   - The reverse sequence \(8, 1, 15, 10, 6, 3, 13, 12, 4, 5, 11, 14, 2, 7, 9, 16\) also satisfies the conditions.

The final answer is \(\boxed{16, 9, 7, 2, 14, 11, 5, 4, 12, 13, 3, 6, 10, 15, 1, 8}\) and its reverse \(\boxed{8, 1, 15, 10, 6, 3, 13, 12, 4, 5, 11, 14, 2, 7, 9, 16}\).
