A particulaly interesting feature of period doubling is the ratio between consecutive period doubling intervals, it is a constant known as the Feigenbaum number.

Feigenbaum Constant δ = 4.66920 16091 02990 67185 32038 20466 20161 72581 85577 ....

The second Feigenbaum constant (sequence A006891 in OEIS),
