 OFFSET 1,2 COMMENTS The next term, if it exists, is greater than 100000. - Ryan Propper, Aug 31 2005 No further terms less than 1000000 using the same method Donovan Johnson explains in A175525. LINKS EXAMPLE 25 divides the sum of digits of 8^25 (i.e., 3+7+7+7+8+9+3+1+8+6+2+9+5+7+1+6+1+7+0+9+5+6+8 = 125), so 25 is in the sequence.
