Table of n, a(n) for n=1..29.

EXAMPLE

a(7)=2 because there are two different values. ( 10 and 6 ):

m_1=50, m_2=80, 10 = A007947(50) = A007947(80) and A056239(50) = A056239(80) = 7.

m_1=54, m_2=72, m_3=96, 6 = A007947(54) = A007947(72) = A007947(96) and A056239(54) = A056239(72) = A056239(96) = 7.
