Iterated continued fraction for CMRB
Cf. Talk:Convergents constant — See what happens if you use those convergents in a generalized continued fraction, then use the new convergents in another generalized continued fraction, then... ad infinitum! This is a work in progress.
Continued fraction for CMRB
Continued Fraction for CMRB=
Notice in the numerators and denominators that
- 0+1 != 3, 1+3 != 31; (2 false)
- 3+31 = 34, 31+34 = 65; (2 true)
- 34+65 != 294; (1 false)
- 65+294 = 359, 294+359 = 653, 359+653 = 1012; (3 true)
- 1012+ 1665 != 15997, 15997+33659 != 421570, 421570+15327153 != 31531105; (3 false)
- 31531105+78389363 = 109920468; (1 true)
- 109920468+188309831 != 3311187595; (? false)
- ...
Is there a pattern?
I think what appears as a pattern is only the partial quotients {3, 10, 1, 1, 4, ...} of the continued fraction itself!
- 3*1+0 = 3, 3*5+1 = 16; (3)
- 10*3+1 = 31, 10*16+5 = 165; (10)
- 1*31+3 = 34, 1*165+16 = 181; (1)
- 1*34+31 = 65, 1*181+165 = 346; (1)
- 4*65+34 = 294, 4*346+181 = 1565; (4)

Is this notable? It might just be a fact for all numbers; I haven't checked. Using the partial denominators as multiples of the (n-1) "partial denominator's numerator and denominator," and add the n-2 "partial denominator's numerator and denominator," we get partial denominator n. I mean the following:

This is just getting back the partial quotients of MRB constant#Continued fraction for CMRB...
- {0, 5, 3, 10, 1, 1, 4, 1, 1, 1, 1, 9, 1, 1, 12, 2, 17, 2, 2, 1, 1, 17, 1, 6, 4, 1, 3, 3, ...}

Update for the MRB constant article
Mathworld has added some sums and integrals for the MRB constant that might be useful, or proofs of which would also be great, on the OEIS wiki page:
http://mathworld.wolfram.com/MRBConstant.html.
Proofs in some form are found in my post at https://community.wolfram.com/groups/-/m/t/366628?p_p_auth=SlzqS8Nx. 06:02, 24 March 2020 (EDT)
