problem

Let P1P2…P24P_1P_2\ldots P_{24} be a regular 2424-sided polygon inscribed in a circle ω\omega with circumference 2424. Determine the number of ways to choose sets of eight distinct vertices from these 2424 such that none of the arcs has length 33 or 88.
Plain-text mathematical notation (without MathML)
Let P₁P₂…P₂₄ be a regular 24-sided polygon inscribed in a circle ω with circumference 24. Determine the number of ways to choose sets of eight distinct vertices from these 24 such that none of the arcs has length 3 or 8.
Original LaTeX notation
