Sloane's On-line Encyclopedia of Integer Sequences has the following entry:
A110375 Numbers n such that Maple 9.5, Maple 10 and Maple 11 give the wrong answers for the number of partitions of n.
11269, 11566, 12376, 12430, 12700, 12754, 15013, 17589, 17797, 18181, 18421, 18453, 18549, 18597, 18885, 18949, 18997
I wonder whether that can be extended to Maple 12 as well (I don't have it to check.)
