 OFFSET 1,8 COMMENTS With sequences constructed of successively larger square matrices (cf. A074279), a(n) will return the distance of n from the left edge of the matrix that n is located in, with 0 standing for the leftmost column (please see the Example section). A237452 gives the corresponding row index. A238013 and A121997 give these same row and column indices, starting the numbering with index 1. - M. F.
