| Mar 4, 2023 at 10:12 | comment | added | P.Labarque | @Brendan: Yes, the bold sentence is the question. And in fact I'm only interrested in it for maximal planar polygons without separating triangles. What follows (included the drawings) is peripheral information, not essential for it. And of coarse a trangulated planar polygon has at least two ears (Gary Meister, 1975 and Max Dehn circa 1899, Wikipedia). | |
| Mar 4, 2023 at 1:06 | comment | added | Brendan McKay | Your use of "possible" and "impossible" is confusing, and "one" is also unclear. Does your bold sentence mean "Is it always possible to choose a hamiltonian cycle so that at least one of the polygons has only two ears?" (After noting that less than two ears never happens; this is equivalent to a non-trivial tree having at least two leaves.) | |
