A154962


The terms of this sequence are integer values of consecutive denominators (with signs) from the fractional expansion (using only fractions with numerators to be positive 1's) of the BBP polynomial ( 4/(8*k+1)  2/(8*k+4)  1/(8*k+5)  1/(8*k+6) ) for all k (starting from 0 to infinity); for k>=1 the ErdosStraus conjecture is applied to the first fraction  so it is always replaced by exactly three fractions.

COMMENTS

This sequence is different from A154925, where the first fraction for k>=1 is expanded with Egyptians fractions, using R.Knott's converter calculator #1 (http://www.maths.surrey.ac.uk/hostedsites/R.Knott/Fractions/egyptian.html#calc1)
