The paper continues the studies of the performance of the thresholding greedy algorithm (TGA) against approximations restricted to vectors supported on intervals and vectors with constant coefficients Consecutive greedy bases are introduced and characterized, and new characterizations of almost greedy and squeeze symmetric Schauder bases are provided. Some cases involving greedy-like properties with constant~1 are investigated, and the related notion of \((A, \tau)\)-property is studied.
