Bijective club! And yes, the ones from delayed bases are allowed Also, unary will not be here. I know unary is bijective and all, but it's not gonna be here since bijective unary is normal unary. If normal unary was non-bijective (using oly the digit 0 instead of 1), then it would be confusing, because the digit "0" would represent 0₁₀ and 1₁₀.
