Most scientists would call that a 68-gon. You can also call it a hexacontakaioctagon.
There are: 0.5*(682-(3*68)) = 2210 diagonals
A 68-sided polygon is called an "68-gon." The naming convention for polygons follows the Greek numerical prefixes, where the number of sides is combined with the suffix "-gon." In this case, "hexacontakaiheptagon" is the technically correct term, but "68-gon" is more commonly used for simplicity.

Polygons with 61 to 69 sides are referred to by specific names based on the number of sides they have. A 61-sided polygon is called a "hexacontakaihenagon," a 62-sided polygon is a "hexacontakaihenagon," a 63-sided polygon is a "hexacontatrihenagon," a 64-sided polygon is a "hexacontatetragon," a 65-sided polygon is a "hexacontapentagon," a 66-sided polygon is a "hexacontaxihexagon," a 67-sided polygon is a "hexacontaseptagon," an 68-sided polygon is a "hexacontaoctagon," and a 69-sided polygon is a "hexacontanovagon." These names are derived from Greek numeral prefixes combined with the suffix "-gon."
