NCAA basketball questions?

How many games is in a regular season for college basketball,and how many if any teams in NCAA basketball have gone undefeated? and in what years?

Regular season could be anywhere from 23 to 29 games depending on the team. Many teams have gone undefeated. UCLA, Indiana, UNC, Duke, UNLV, Kansas, Kentucky and i'm sure i'm missing some. UCLA won the NCAA several years in a row including not losing a game over a 3 year span.
the last time a team went undefeated all year without a loss was the university of Indiana Hoosiers men's basketball team coached then by the general himself Bobby Knight and the team finished that year at 37 and 0
2003, st.joes went 33-0 i believe and then they lost in the tourney. i think stanford also ended the season undefeated, but then lost in the pac 10 tourney and then lost in the second round to alabama. there are around 30 games in the regular season. then conference tourney and the big dance...
It varies slightly, but usually around 30-32, not including the post season conference. Indiana was the last go undeafted in 1976, a few teams before that, UCLA comes to mind.
