%I A113459 #8 Mar 30 2012 17:38:08 %S A113459 1,2,3,5,5,7,7,11,11,11,11,13 %N A113459 Least number that begins an arithmetic progression of n numbers with the same prime signature. %C A113459 Initial terms of arithmetic progressions described in A113460. - _N. J. A. Sloane_, Oct 18 2007 %C A113459 Conjecture: For n > 1, a(n) = A007918(n). - _David Wasserman_, Jan 08 2006 %C A113459 I disagree with that conjecture! Ignoring the initial terms, this will agree with A007918 up to some point and then (presumably) drop below A007918. The initial term in the arithmetic progression (of length n) must be >= n, but it is likely to be less than A007918(n) if n is large. - _N. J. A.
