The Wikipedia ref link to NED says (Mpc):
Min. 2.450
Mean 7.225
Median 7.800
Max. 12.200
Std. Dev 2.12
So million light years (Mly): mean 23.5, median 25.4, +- 6.9
That makes Wikipedia text itself very wrong (32 Mly) and the article (27 Mly) slightly better, but not actually in the mean-median range.
