COMMENTS
The sequence is bounded above for odd n by (((n-1)/2)^n)*(2^((n-1)/2)).
Growth appears to be slightly faster than exponential, but irregular, with odd-numbered terms larger than the trend.

EXAMPLE
For n=3, the only solution is 2,2,2.
For n=4, the 5 solutions are 3,3,3,3 and the four permutations of 3,3,3,2.
