“…the pump journal of undergraduate research 4 (2021), [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] We see in Figure 2 that the original frame is robust to the loss of any two vectors. On the other hand, the sequence F = {f 1 , f 2 , f 3 , f 3 } is a frame for R 2 that represents the diamond graph but which is robust to only one erasure, since reconstruction would be impossible in the event that both x, f 1 and x, f 2 were lost.…”
