Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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