comment Why this difference of 25?
The sequence, so far, is (2, 8, 22, 166, 788, 4962, 29922, 179682, 688078, 7060198) -- they are not all of the form 6p. They are just record setters. E.g. the third term = 22 because 22 mod 11+2 = 9 -> 9 mod 3+3 = 3 -> 3 mod 3 = 0, and 22 is the smallest number with a depth of 3. That said, it may still not be an interesting sequence. :)

Thank you. If you care to, you could create an OEIS account and add your explanation to the "Comments" section of the draft edit of A238530. If not, I will do so.

@Ross: Sorry. I forgot the sequences weren't published yet. They should be soon.

Nevermind. I still had k=1 when I tried 1033. Works perfectly.

Thank you, Robert: f[x_, k_] := Floor[x/7^k]*8^k + Sum[(Mod[Floor[x/7^m], 7] + 1)*8^m, {m, 0, k - 1}]; For[lst = {}; i = 0, i < 100, i++, AppendTo[lst, {f[i, 1], BaseForm[f[i, 1], 8]}]; ]; lst EDIT: did I get that right? I get 1033 -> 2011

Sorry. I thought "produce numbers" was clear. I'll edit. P.S. I up-voted your answer.

comment How to avoid base-$8$ numbers that contain zeros?
Yes, the leading zero is allowed, but nowhere else. I'm hoping for an answer like f(k,a,b) -> all such non-zero base-8 numbers in range a to b of length k, but maybe that isn't possible.

comment How can I draw a polygon from a set of angles?
yes, the legs are length 1 and the hypotenuse is $\sqrt 2$. I'm not familiar with lattice points. I though using vectors might be another way -- if the angle is congruent to 0 mod 30, draw a vector of length 1, else draw a vector of length $\sqrt 2$.

Sorry. Too many tabs open, I thought I was posting to mathematica. Should I delete, or is this still an interesting math question?
