consider i being Element of NAT such that
A1: 1 <= i and
A2: i <= len (Gauge C,n) and
A3: N-min (L~ (Cage C,n)) = (Gauge C,n) * i,(width (Gauge C,n)) by Th25;
take i ; :: thesis: ( 1 <= i & i <= len (Gauge C,n) & (Gauge C,n) * i,(width (Gauge C,n)) in rng (Cage C,n) )
thus ( 1 <= i & i <= len (Gauge C,n) & (Gauge C,n) * i,(width (Gauge C,n)) in rng (Cage C,n) ) by A1, A2, A3, SPRECT_2:43; :: thesis: verum
