Instead of . we shall define a variable . which equals +1 when . = ., and which equals ?1 when . = .; its aymptotic values would be . = ? 1 and . = + 1. We write . = . + . and will determine . and . such that . has the desired asymptotes:

Furthermore, we generated a two-dimensional array of four distinct types of two-fold rotocenters by postulating a two-fold rotocenter off the row of two-fold rotocenters already generated (Figure 3-8).
