Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,3)(13,14,17,22,18,23,16,21)(15,19,24,20,26,28,25,27);(1,2,4,3)(5,6)(7,9)(8,11)(10,12)(13,15,16,25,18,26,17,24)(14,19,21,27,23,28,22,20);(6,9)(7,12)(10,11)(13,15,18,26)(14,20,23,27)(16,24,17,25)(19,21,28,22);(1,3,4,2)(13,16,18,17)(14,21,23,22)(15,24,26,25)(19,20,28,27)
