Statistics of the precursor stellar populations of the 4th-, 5th-, and 6th-ranked galaxies by group class.

Group class	Number of	m₄(z_fin)			m₅(z_fin)			m₆(z_fin)

Notes.

m_i(z_fin) < 0.5 m_j(z_ini), with i = 4, 5, 6 and j ≥ i.

0.5 m_j(z_ini)≤m_i(z_fin)≤0.9 m_j(z_ini).

m_i(z_fin) > 0.9 m_j(z_ini).
