A variation on a previous theme:

Base	Number	Number in Base 10
2	12	1
3	23	2
4	3124	54
5	4135	108
6	4126	152
7	651427	16200
8	76251348	2042460
9	82715369	4416720
10	986731210	9867312
Still churning - these O(nn) algorithms really soak up the CPU time... (I later hit Ctrl-C, so all numbers after this point are from coldtortuga)
11	A9876241311	2334364200
12	B935217612	421877610
13	CBA9584721313	1779700673520

(note that the intuition I gave for 12 means that 13 will most likely be some friggin huge number, due to its primeness)
