Abstract
In their article ‘Tilings by regular polygons’, B. Grünbaum and G. C. Shephard [1] conjecture that there are 19 equitransitive edge-to-edge tilings by regular convex polygons. We prove that there are 22 equitransitive edge-to-edge tilings by regular convex polygons, and it turns out that 3 of them are 1-equitransitive, 13 are 2-equitransitive, 5 are 3-equitransitive and 1 is 4-equitransitive.
