Stamps with different designs that are attached to one another are called "Se-tenant" by stamp collectors. Se-tenant stamps began as issues of separate designs that were simply attached to one another which may be either one or more. They may have their attachments in horizontal or vertical strips or both types in one block of four. Sometimes, they may have attachments even at corner points.  Moreover, we also find issues where the stamps are part of a larger continuous design.There are differing ways of preparing a se-tenant sheet. They may be joined in a (1) Horizontal pair of two (2) Vertical strip of three (3) Horizontal strip of three (4) Vertical strip of four (5) Horizontal strip of four (6) Variety of same Se-tenant stamps with block of four and vertical & horizontal strips (7) Horizontal strip of five (8) Vertical Strip of five (9) Horizontal & vertical both pattern in one block (10) Block of four with separate design stamps (11) Block of four forming continuous and compact design (12) Vertical strip of two continuous and compact design (13) Horizontal strip of two continuous and compact design (14) Four Se-tenant Stamps forming a Diamond shape (15) Se-tenant stamps forming an odd shape (16) Joint issue Se-tenant stamps with subject of another country on one stamp (17) Se-tenant Stamps with tete-beche format.
