Mathnet is a parody of Dragnet, in which the main characters are mathematicians who use their mathematical skills to solve various crimes and mysteries in the city.
Both Mathnet and Square One went off the air in 1994 (it was rerun until then after the final 1992 season was completed), reappearing from 1999-2003 on the cable television network Noggin, a joint venture of Nickelodeon and CTW.
