 No re-init of JI between
 the two calls.

T = 0;
SERIE(20, 20, 8, 6, ELIRR); // fig. 22, not drawn
T = 1;
SERIE(20, 20, 8, 6, ELIRR); // fig. 23
// ELSE branch: LINE(J1, J2), close LINE(P1, Q1).
// K = N+1 corners.

Approximate rendering. P. 194: the same block as figure 22, then T = 1 and SERIE again, without reloading the generators. The edges are diagonals; each LINE(J1,J2) replaces the right-angle pair of figure 22. The figures stand apart more clearly. JS1 and JS2 are the usual values from p. 122, not those of the plate. The sheet stands portrait, as in the scan.
