find the number of symmetric relations on a set of 3 elements.

so say I have A={a,b,c}

so we have relation R on A

which gives us R includes {aRa, aRb, aRc, bRa, bRb, bRc, cRc, cRa, cRb}

then…all of them are symmetric, right? which means we have 9 different symmetric relations on A?

just checking my answer haha. not too sure what to do P:

Anybody out there know the answer? :)
