Talk:First perfect square in base n with n unique digits

From Rosetta Code

Leading zeros ?

Perhaps the 'First perfect square in base 2 with 2 unique digits' is arguably '01' ? Hout (talk) 23:53, 20 May 2019 (UTC)

Ok, kind of weaselly but fair point. Reworded; First perfect square in base 2 with 2 significant unique digits. --Thundergnat (talk) 01:17, 21 May 2019 (UTC)

Proof

The task conjectures that the sum from n=0 to some n of 2n+1 has at least one value of n for every base for which the sum is a number containing all digits in the base. Can you prove this conjecture?--Nigel Galloway (talk) 21:34, 22 May 2019 (UTC)
