Domino and Tromino Tiling
Cover a 2 by n board without gaps or overlaps, using 2 by 1 dominoes and L-shaped trominoes made of three unit squares. Tiles may be rotated. Count distinct tilings modulo 10^9 + 7. Two tilings differ when some pair of side-adjacent cells belongs to a single tile in one tiling but not the other.
