Talk:Achilles numbers

From Rosetta Code

Project Euler 302 asks "How many Strong Achilles numbers are there below 1018?", I think I'll leave that for another day! --Pete Lomax (talk) 19:06, 26 February 2022 (UTC)

Why 1728 is not a achille number ?
1728 = 64 * 27 = 2 puissance 6 * 3 puissance 3
For me it is ok !
thanck. -- VincentArm

For a number to be an Achilles number it must have no perfect roots. 123 == 1728. ∛1728 = 12. --Thundergnat (talk) 16:19, 20 June 2022 (UTC)
Oh yes ! I thought it was only necessary to check the squares. I had forgotten the other powers. Thanks -- VincentArm
