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
10, 100, 1000, 110, 200, 1100, 210, 1110, 1200, 2100, 1210, 2110, 2200, 3100, 2210, 3110, 3200, 12200, 3210, 12210, 13110, 13200, 22200, 13210, 22210, 23110, 23200, 32200, 23210, 32210, 33110, 33200, 42200, 33210, 42210, 43110, 43200, 133200 (list; graph; refs; listen; history; text; internal format)

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
