Use the PI -> WYE conversion formula for R1,R2,and R5. That simplifies
it...
ra=r1*r2/(r1+r2+r3)
rb=r1*r5/(r1+r2+r3)
rc=r2*r5/(r1+r2+r3)
Then, r = ra + parallel(rb+r3,rc+r4)
so
r = (r1 r2 r3 + r1 r2 r4 + r1 r2 r5 + r1 r3 r4 + r2 r3 r4 + r1 r4 r5 +
r2 r3 r5 + r3 r4 r5) / (r1 r3 + r1 r4 + r2 r3 + r1 r5 + r2 r4 + r2 r5 +
r3 r5 + r4 r5)

One cannot inquire into the foundations and nature of mathematics without
delving into the question of the operations by which the mathematical
activity of the mind is conducted. If one failed to take that into account,
then one would be left studying only the language in which mathematics is
represented rather than the essence of mathematics.
