Yep, I eventually stumbled on that. I've already added the other Rabbit constant to my numbers catalog at mrob.com/pub/math/numbers.html#l0_83921 I wrote about the Rabbit constant in July 2001: http://web.archive.org/web/20010720113825/http://home.earthlink.net/~mrob/pu... and of course I completely forgot about it!

We can also obtain the sequence from removing the first two terms of the rabbit sequence.

1 10 10|1 10|110 10|110101 10|11010110110 ...

(This is equivalent to the first definition, as the string '10' acts as a factory for producing an extra '1' at each stage.)

...

So, we have M = 4(R - 1/2) = 4R - 2, where M is the Munafo constant 0.839213... and R is the Rabbit constant:
