assume SCM+FSA-Data*-Loc meets SCM-Memory ; :: thesis: contradiction
then consider x being set such that

suppose x in SCM-Data-Loc ; :: thesis: contradiction
then consider k being Element of NAT such that
A6: x = [1,k] by AMI_2:32;
consider y, z being set such that
A7: y in {0 } and
z in NAT and
A8: x = [y,z] by A4, A6, ZFMISC_1:103;
y = 0 by A7, TARSKI:def 1;
hence contradiction by A6, A8, ZFMISC_1:33; :: thesis: verum

suppose x in NAT ; :: thesis: contradiction
then consider k being Element of NAT such that
A9: x = k ;
thus contradiction by A1, A9, XBOOLE_0:def 5; :: thesis: verum
