Presentation

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

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

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