No.
A regular octagon will not tessellate but an irregular one can.
circles and octagon do not tessellate as they overlap each other or leave spaces between them.
It is tessellating where there are no gaps or overlaps.
no it cant be unless you use pentagons and octagons like on a soccer ball * * * * * That is an unbelievably rubbish answer! Tessellation - unless otherwise specified - refers to covering a 2-d surface, not the surface of a sphere. Normal soccer balls do not have pentagons and octagons but pentagons and hexagons.
A scheme for suing multiple copies of a regular polygon so as to cover a plane without gaps or overlaps.
A regular octagon can tessellate the plane when combined with regular squares. By placing a square in the center of the octagon and surrounding it with eight octagons, the shapes can be repeated infinitely, filling the plane without gaps or overlaps
