Help - diallell problem

Ive got a problem to which a solution would be a great help to me.
I work in plant breeding in which data arrays more known as diallelles are commonly used for planning new crosses.

On the X and Y axis of these arrays the different lines are listed and crosses between the lines are somehow noted in the array.
These arrays can be quite big and complicated and Im in need of a function that automatically list all noted crosses in the array.

Is this possible ?

See the attached example.

use array formula (cse)

=INDEX($A$1:$A$14,MOD(SMALL(IF(LEN($B$7:$K$14),($B$6:$K$6*1000000)+ROW($B$7:$K$14)),ROW(1:1)),1000))&SMALL(IF(LEN($B$7:$K$14),$B$6:$K$6),ROW(1:1))

Great, thanks guys!
