Dear  seqfans,

n  =  (p_0 ^ a_0) *(p_1 ^ a_1)* ... *(p_m ^ a_m)  =   a_0 * (B^0) + a_1 * (B^1)  + ... +  a_m * (B^m) .
p_i   i-th prime ;  a_(i<m) >=0, a_m >=1 , B integers.

The equation has positive-integer solutions  [n,B]  :  
[3,3]   [6,5]   [10,3]   [12,10]   [24,21]   [27,9]   [36,17]   [48,44]   [71,34]   [96,91]   [100,7]   
(submitted to OEIS )

Are there any other numbers n>12 for which [n,10]  holds ?

Ctibor
