%N Modified LookandSay sequence where 2 is the largest number that may be used.
%C The ratio r(n) of the number of "1"s to the number of "2"s in the sequence converges to (4*phi^(3/2)+5*phi+sqrt(phi)+3) / (4*phi^(3/2)+5*phi+3*sqrt(phi)+3) = 0.890054... as n goes to infinity, where phi = (1+sqrt(5))/2 is the golden ratio. [From _Nathaniel Johnston_, Jan 13 2011]
