 A055992 n written efficiently in natural numbers base, i.e., in form ...wxyz where n =1*z + 2*y + 3*x + 4*w + ... with z < 1, y < 2, x < 3, w < 4, ... 1

 OFFSET 2,1 LINKS Table of n, a(n) for n=2..39. Index entries for sequences related to final digits of numbers EXAMPLE a(9)=1110 since 9 = 4*1 + 3*1 + 2*1 + 1*0 and alternatives such as 100000000 or 11000 are less efficient (while 211 is prohibited because the final digit is too big). CROSSREFS Cf. A055611 for a slightly different definition.
