The Coliseum uses a split-section seating layout where a numbered aisle splits each section into a low and high sub-section. For example, low number seats (1-16) in section 9 are on the left side of the aisle, and high number (101-116) seats are on the right side of the aisle.
Additionally, the highest number seat in each sub-section is adjacent to another sub-section with a different number. For example, seat 116 in section 9, row 47 is adjacent to seat 16 in section 8, row 47. As a result, most rows contain roughly 30 seats per row.
