# 130

This number is a composite.

130 = 5^{1} + 5^{3}. Note the product of the concatenated powers (13) and sum of bases (10). [Gevisier]

Sum of the factorials of the first five terms of the Fibonacci sequence. [Lutz]

130 is the only number equal to the sum of the squares of its first 4 divisors: 130 = 1^2 + 2^2 + 5^2 + 10^2. [Ingala]
