The wedge-dash conformation is the one where the two hands of the carbon atom are in the plane and the rest of the two are above and below the plane accordingly and the anti-gauche confirmation is represented here for the pentane. The drawing looks like:

Challenge Problem 09.78 The two lowest energy conformations of pentane are the anti-anti and the anti-gauche forms, in terms of arrangements around the two central C-C bonds. A recent study analyzed the conformations of 3-heptyne as an "elongated" analogue of pentane, where a carbon-carbon triple bond is "inserted" between C2 and C3 of pentane (J. Phys. Chem. A. 2007, 111, 3513-3518). Interestingly, the researchers found that in each of the two most stable conformations of 3-heptyne, C1 and C6 are...

A recent study analyzed the conformations of 3-heptyne as an “elongated” analogue of pentane, where a carbon-carbon triple bond is “inserted” between C2 and C3 of pentane.[15] Interestingly, the researchers found that in each of the two most stable conformations of 3-heptyne, C1 and C6 are nearly eclipsed (looking down the alkyne group).
