First Feigenbaum Constant: Also known as

The first Feigenbaum constant is also referred to as merely the Feigenbaum constant or Feigenbaum number.

As it was the first to be noticed and investigated, it was inevitably named before the second Feigenbaum constant was identified.

Some sources give it as the Feigenbaum bifurcation velocity.
