Giheks can be combined with bo in the same way as eks:

is equivalent in meaning to Example 14.39 and Example 14.40. Likewise, ke…ke'e grouping can be used after giheks:

is the gihek version of Example 14.47. The same rule about using ke…ke'e bracketing only just after a connective applies to bridi-tails as to sumti, so the first two bridi-tails in Example 14.61 cannot be explicitly grouped; implicit left-grouping suffices to associate them.

Each of the pairs of bridi-tails joined by multiple giheks can have its own set of tail-terms:

is equivalent in meaning to:

The literal English translation in Example 14.63 is almost unintelligible, but the Lojban is perfectly grammatical. mi fills the x1 place of all three selbri; lo rupnu is the x2 of dejni, whereas le cukta is a tail-term shared between dunda and lebna; la djan. is a tail-term shared by dejni and by dunda gi'abo lebna. In this case, greater clarity is probably achieved by moving la djan. to the beginning of the sentence, as in Example 14.53:

Finally, what about forethought logical connection of bridi-tails? There is no direct mechanism for the purpose. Instead, Lojban grammar allows a pair of forethought-connected sentences to function as a single bridi-tail, and of course the sentences need not have terms before their selbri. For example:

is equivalent in meaning to Example 14.50.

Of course, either of the connected sentences may contain giheks:

The entire gek-connected sentence pair may be negated as a whole by prefixing na:

Since a pair of sentences joined by geks is the equivalent of a bridi-tail, it may be followed by tail terms. The forethought equivalent of Example 14.54 is:

Here is a pair of gek-connected observatives, a forethought equivalent of Example 14.57:

Finally, here is an example of gek-connected sentences with both shared and unshared terms before their selbri:
