Presentation

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

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

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