A retention lobe for a ground engaging tip , the retention lobe comprising: a lobe base having a base outline , wherein at least a portion of the base outline lies in a base plane ( P ), wherein the base outline includes a front base edge and a rear base edge opposite the front base edge; and a lobe outer surface spaced from the lobe base and extending from the front base edge to the rear base edge, characterised by the lobe outer surface including: a front lobe outer surface extending from the front base edge obliquely relative to the base plane and toward the rear base edge; an intermediate lobe outer surface spaced from the base plane and extending obliquely from the front lobe outer surface; and a rear lobe outer surface extending obliquely from the intermediate lobe outer surface and terminating at the rear base edge, such that the rear lobe outer surface tapers from the intermediate lobe outer surface toward the base plane, wherein the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface are substantially planar, except where the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface meet one another, where a transition between the lobe outer surfaces forms a corner or a curved transition. a lobe base having a base outline , wherein at least a portion of the base outline lies in a base plane ( P ), wherein the base outline includes a front base edge and a rear base edge opposite the front base edge; and a lobe outer surface spaced from the lobe base and extending from the front base edge to the rear base edge, characterised by the lobe outer surface including: a front lobe outer surface extending from the front base edge obliquely relative to the base plane and toward the rear base edge; an intermediate lobe outer surface spaced from the base plane and extending obliquely from the front lobe outer surface; and a rear lobe outer surface extending obliquely from the intermediate lobe outer surface and terminating at the rear base edge, such that the rear lobe outer surface tapers from the intermediate lobe outer surface toward the base plane, wherein the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface are substantially planar, except where the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface meet one another, where a transition between the lobe outer surfaces forms a corner or a curved transition. a front lobe outer surface extending from the front base edge obliquely relative to the base plane and toward the rear base edge; an intermediate lobe outer surface spaced from the base plane and extending obliquely from the front lobe outer surface; and a rear lobe outer surface extending obliquely from the intermediate lobe outer surface and terminating at the rear base edge, such that the rear lobe outer surface tapers from the intermediate lobe outer surface toward the base plane, wherein the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface are substantially planar, except where the front lobe outer surface , the intermediate lobe outer surface and the rear lobe outer surface meet one another, where a transition between the lobe outer surfaces forms a corner or a curved transition. <EOS>
