Circle of Sarkisov Links on a Fano 3-fold

For a general Fano 3-fold of index 1 in the weighted projective space (1, 1, 1, 1, 2, 2, 3) we construct two new birational models that are Mori fibre spaces in the framework of the so-called Sarkisov program. We highlight a relation between the corresponding birational maps, as a circle of Sarkisov links, visualizing the notion of relations in the Sarkisov program.
