The semiprime $28222149$ is a semiprime $S=A*B$ (with $A=3$ and $B=9407383$) such that
-$A.B$
-$B.A$
-$S.A$
-$S.B$
-$A.S$
-$S.A.B$
-$S.B.A$
-$A.S.B$
-$A.B.S$
-$B.S.A$
-$B.A.S$
are all semiprime. (Dots here means concatenation.)
It would be a 'perfect' result if $B.S$ were also a semiprime. Unfortunately, $B.S$ is not semiprime.
I've checked semiprimes up to $10^{10}$, and I didn't find a semiprime which gives a 'perfect' result. Could you find a semiprime with 'perfect' result?
