Hi all,

I am having a problem with the connectivity array returned by the
triangulate procedure. The first part of the array, which contains the
indices for each node, looks like this:

59 65 69 75 83
88 94 101 105 112 118
123 128 132 139 145
151 156 163 170 175 184
191 195 200 205 209
215 221 228 233 237 244
248 254 259 266 274
279 286 290 295 302 305
305 312 319 326 331
337 343 348 353 359 363
368 373 379 385

The problem is that the value 305 is repeated; given the stated
instructions in the online help, this doesn't make sense.

"To obtain the adjacency list for node i, extract the list elements from
LIST[i] to LIST[i+1]-1." I've plotted up my triangles and nothing seems
amiss - does anyone have a clue what is going on here? Thanks!
