Todd_coxeter example of Groups section reveals
two problems:
First:
(%i1) symnet(n):=cteate_list(if (j-1)=1 then (p(i,j))^^3 else
if (not i=j) then (p(i,j))^^2 else p(i,j), j, 1, n-1, i, i, j);
<3>
(%o1) symnet(n) := cteate_list(IF j - 1 = 1 THEN p(i, j)
<2>
ELSE (IF NOT i = j THEN p(i, j) ELSE p(i, j)), j, 1, n - 1,
i, i, j)
Keywords if, then, else are printed in UC. Is this CS bug?
Second:
(%o9) {Array: ixnum #(0 2 1 3 7 6 5 4 8 11 17 9 12 14 13 20 16 10 18 19
15 0 #
0 0 0 0 0 0 0
0 0 0 0 0 0 0)}
Take a look at this final array. Here ixnum actually
should be fixnum. Stange.
