Presentation

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

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

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