COMMENT

Since A057113 is generated based on A057112(n) and succesive transpositions, we can be assured that A141826(n) will always map (using A055089)to permutation with an even number of transpositions (applicable, e.g. to the Icosahedron and truncated icosahedron studied in the Geometry Center at http://www.scienceu.com/geometry/facts/solids/handson.html ).

EXAMPLE

A057113(n)is 0 1 4 5 3 2 12 13 16 22 19 18 20 10 7 6 8 14 15 9 11 21 23 17 77... so the sequence begins 0 4 3 12 16 19 20 7 8 15 11 23 77 ...
