11 Use red, yellow, and blue to color the 9 small squares labeled $1,2,3, \cdots, 9$ (as shown in the figure), such that any two adjacent (sharing a common edge) small squares are colored differently, and the numbers “3, 5, 7” are colored the same. The total number of coloring methods that meet the conditions is $\qquad$ (answer with a specific number).
$113, 5, 7$ have the same color, then they have 3 coloring methods. At this time, if $2, 4$ have the same color, then they have 2 coloring methods, thus number 1 has 2 coloring methods; if $2, 4$ have different colors, then they have 2 coloring methods, and number 1 has only 1 coloring method. By the symmetry of the square, there are a total of coloring methods $3 \times(2 \times 2+2 \times 1)^{2}=108$ (ways).
