Reference for Yoma 139:21

אמר רבא לא משכחת לה מתקנתא אלא או לרבי אליעזר דתנא בדבי שמואל או לרבי עקיבא כדתוספתא

<big><b>GEMARA: </b></big>The question was raised: How does he [R'Akiba] mean: They [the seven lambs] were offered up together with the daily whole-offering of the morning, whereas the bullock for the whole-offering and the he-goat which is offered up outside were offered up together with the daily whole-offering of the afternoon; or did he mean, perhaps, this: they were offered up together with the daily whole-offering of the morning and together also with them the bullock for the whole-offering, whereas the he-goat which is offered up outside is offered up together with the daily whole-offering of the afternoon?<span class="x" onmousemove="('comment',' R. Akiba's statement is not clear enough. Either of the two interpretations are possible, dependent on where the end of the clause is placed.');">¹⁷</span> Furthermore, when, according to R'Eliezer who omits reference to him, is the bullock for the whole-offering being sacrificed?
