The person I was responding to had a two-ish step problem 1) find a number with a binary representation that looks like Mickey 2) find an index for that number in pi that looks like the copyright symbol. Both are conceivably possible because pi is infinite and it's decimal places contain all numbers somewhere but we only know so many actual digits. Since we're dealing with the index of the number from step 1 though the number of bits we have to find the copyright symbol in is only log_2(22,459,157,718,361) ~= 45 because it's the index we're after. That gives a roughly 7x7 grid to draw © in which is pretty limited and might be the minimum viable for a clean ©. (and that's been a touch generous by allowing 0 padding on the front of the number)
