Presentation

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

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

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