A367344 Compute the commas sequence starting at 1, as in A121805, except do the calculations in octal. The terms are written here in octal (see also A367343).

1, 12, 35, 106, 167, 261, 273, 326, 412, 436, 523, 560, 565, 643, 702, 731, 750, 757, 1050, 1051, 1062, 1103, 1134, 1175, 1246, 1327, 1420, 1421, 1432, 1453, 1504, 1545, 1616, 1677, 1770, 1771, 2003, 2035, 2107, 2201, 2213, 2245, 2317, 2411, 2423, 2455, 2527, 2621, 2633

Table of n, a(n) for n=1..49.

Example

The first three terms are 1, 12, 35 in octal, and we check that around the first comma we see 1,1_8 which becomes 11_8 = 9_10, and 1_10 + 9_10 = 10_10 = 12_8 = a(2).
Around the second comma we see 2,3_8, which becomes 23_8 = 19_10, and indeed 12_8 + 23_8 = 10_10 + 19_10 = 29_10 = 35_8 = a(3).
