" Jenny is standing between Paco and Maria"
..........P.......J.......M or M..........J...........P (we still know nothing about Tim (T)

"Paco’s position in line is an odd number"
Paco's gotta be in the 1st or 3rd position then
PTJM PJTM PJMT MJPT are the only 3 possibilities now

"Tim is not standing on either end of the line, and he is in front of Jenny"
