theorem Th13: :: CIRCCMB2:13

for S1, S2, S being non empty non void Circuit-like ManySortedSign st InputVertices S1 misses InnerVertices S2 & S = S1 +* S2 holds
for A1 being non-empty Circuit of S1
for A2 being non-empty Circuit of S2
for A being non-empty Circuit of S st A1 tolerates A2 & A = A1 +* A2 holds
for s being State of A
for s1 being State of A1 st s1 = s | the carrier of S1 holds
for n being natural Number holds (Following (s,n)) | the carrier of S1 = Following (s1,n)
