%N Triangle read by rows, consisting of distinct positive integers such that the absolute difference of (horizontally or vertically) adjacent numbers is a (least possible) distinct prime.

%C If there are two numbers that minimize the difference, the smaller is chosen. The sequence ends when it becomes impossible to simultaneously minimize the vertical and horizontal differences.

%Y Cf. A093900, A093901, A093902.
