 A Number Pyramid is composed of the 10 different numbers 0-9 with a top row of 1 number resting on a second row of 2 sitting on a third row of 3 supported by a bottom row of 4. For example, a Number Pyramid could be:      0     1 2    3 4 5   6 7 8 9 Given the clues below, can you determine the composition of Number Pyramid 4? The middle number in row 3 is less than at least two of the numbers in the bottom row of the Pyramid. The rightmost number in row 4 is greater than the number to its immediate left in the row. The difference between the higher and lower numbers in row 2 is 2. In row 4, subtracting the higher and the lower of the two leftmost numbers equals 3. The three numbers in row 3 sum to 20, as do the four numbers in row 4. The sum of the number in row 1 and the numbers leftmost in rows 2, 3, and 4 totals 9.
