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