[https://projecteuler.net/problem=302 Project Euler 302] asks "How many Strong Achilles numbers are there below 10<sup><small>18</small></sup>?", I think I'll leave that for another day! --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 19:06, 26 February 2022 (UTC)
Why 1728 is not a achille number ? <br>
1728 = 64 * 27 = 2 puissance 6 * 3 puissance 3 <br>
For me it is ok ! <br>
thanck. --[[User:VincentArm| VincentArm]]<br>
:For a number to be an Achilles number it must have no perfect roots. 12<sup>3</sup> == 1728. ∛1728 = 12. --[[User:Thundergnat|Thundergnat]] ([[User talk: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 --[[User:VincentArm| VincentArm]]
