 OFFSET 1,1 COMMENTS See A099542 for definition of Rhonda numbers and for some links. LINKS Reinhard Zumkeller, Table of n, a(n) for n = 1..1000 Eric Weisstein's World of Mathematics, Rhonda Number EXAMPLE The product of the base 15 digits of 2392 is 10*9*7=630. The sum of the prime factors of 2392 is 3*2+13+23=42 and 630=15*42. So 2392 is a Rhonda number to base 15. PROG (Haskell) a100974 n = a100974_list !! (n-1) a100974_list = filter (rhonda 15) \$ iterate z 1 where    z x = 1 + if r < 14 then x else 15 * z x' where (x', r) = divMod x 15 -- Function rhonda as in A099542. -- Reinhard Zumkeller, Mar 07 2015 CROSSREFS Cf.
