@Rudic: The actual input data that I have is much bigger than this! It might be possible to have 1000 permutations.
Actually my worries is if it's possible to do this simulation and repeat it million times for instance. If it does not make sense I have no other choice rather than disregarding the similarity for sum of each rows and just check for similar sums for each column.

@bakunin: the difference between this problem and "8-queens-problem" is that first: in 8-queens there is just one position for each row and column to have value '1', but here it's more and varies. Second: Here we take those variants which are symmetrical or mirror as well since each column has different meaning.

NAME
zlacrm.f - SYNOPSIS
Functions/Subroutines subroutine zlacrm (M, N, A, LDA, B, LDB, C, LDC, RWORK) ZLACRM multiplies a complex matrix by a square real matrix. Function/Subroutine Documentation subroutine zlacrm (integerM, integerN, complex*16, dimension( lda, * )A, integerLDA, double precision, dimension( ldb, * )B, integerLDB, complex*16, dimension( ldc, * )C, integerLDC, double precision, dimension( * )RWORK) ZLACRM multiplies a complex matrix by a square real matrix. Purpose: ZLACRM performs a very simple matrix-matrix multiplication: C := A * B, where A is M by N and complex; B is N by N and real; C is M by N and complex. Parameters: M M is INTEGER The number of rows of the matrix A and of the matrix C. M >= 0. N N is INTEGER The number of columns and rows of the matrix B and the number of columns of the matrix C. N >= 0. A A is COMPLEX*16 array, dimension (LDA, N) A contains the M by N matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >=max(1,M). B B is DOUBLE PRECISION array, dimension (LDB, N) B contains the N by N matrix B. LDB LDB is INTEGER The leading dimension of the array B. LDB >=max(1,N). C C is COMPLEX*16 array, dimension (LDC, N) C contains the M by N matrix C. LDC LDC is INTEGER The leading dimension of the array C. LDC >=max(1,N). RWORK RWORK is DOUBLE PRECISION array, dimension (2*M*N) Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
