OEIS contributions, including:

- miscellaneous new sequences:
- new sequences partly taken from published sources:
- A279903, Hausdorff dimension of
*E*_{{1,2}}; - A282137, a linear recurrence related to the Khmelnik representation of integers, A066321;
- A279402-A279409, independence and domination numbers for toroidal chess graphs; also, corrections to A274947 and hence A250000, squares attacked by queens;
- A288535-A288537, generalization of Conway's RATS to other bases;
- A274137, МЩ;
- A273975, a 3D array of "
*k*-nomial coefficients";

- A279903, Hausdorff dimension of
- contributions to miscellaneous nice sequences invented by other people:
- programs for Conway's enumeration of rational knots A122495 and links A173637;
- nested log formula for A278813, A278452, and related sequences;
- a program for A277795, Equisetum-like graphs;
- corrections and program for A267794, relative of van Eck's sequence;
- some terms and an asymptotical formula for A277828, number of coin tosses to get a run of connsecutive identical result with probability >1/2;
- realizing that A132101 is a 1D analog of A250001;
- contributions to A282390, the tripling polyminoes;
- contribution to A089618, "a Khinchin sequence";
- a term for A283075, times measurable by burning ropes;
- program for A173637, the curling number of the Thue-Morse sequence;
- program for A287150, the fairest turn sequence for 3 players, which is in some sence a generalization of the Thue-Morse sequence;
- contributions to Zorach additive triangle A035312 and related sequences, including A136561;

- cellular automata:
- physics:
- what can be called editorial work:
- editing of A054434, the Rubick's cube related sequence with unknown definition (I am particularly proud of solving this mistery);
- a program and dscussion of binary Barker codes A276690;
- a reference for an old sequence A020496;
- crossrefs between different versions of A035607 (it turned out that there are 5 versions of the same array, mostly not cross-referenced);
- discussion about the balance between chemical and mathematical definitions of A134818;
- clarifications to A040004 and A288677, related to Waring's problem mod
*n*(it took time to verify that the difference in one term only is not a mistake); - some other discussions.

The primary mechanism of decision-making in the OEIS community is *NJAS ex machina*.
