Triangle ABC: a = BC, b = AC, c = AB (c > b > a)Code:C B 20 E 15 D 20 F 64 A

CD bisects angle ACB, then CE bisects angle BCD and CF bisects angle ACD.

d = CD, e = CE and f = CF.

a = 40, b = 96, c = 119, d = 30, e = 30, f = 40.

The bisectors divide base AB in integer lengths as shown: 20 + 15 + 20 + 64 = 119.

This is the lowest primitive case of these, lowest being determined by side BC.

What is the next primitive case?

HINT: a <> f and d <> e.
