theorem Th23: :: JORDAN1I:23

for f being constant standard clockwise_oriented special_circular_sequence
for G being Go-board
for k being Nat st f is_sequence_on G & 1 <= k & k + 1 <= len f & f /. k = E-max (L~ f) holds
ex i, j being Nat st
( [i,(j + 1)] in Indices G & [i,j] in Indices G & f /. k = G * (i,(j + 1)) & f /. (k + 1) = G * (i,j) )
