This algebra is one of the four chiral $\\mathcal W$-algebra extensions of $\\mathfrak{so}(2,3)$ and is a generalisation of the chiral $\\mathfrak{bms}_4$ algebra responsible for soft theorems of graviton MHV amplitudes in ${\\mathbb R}^{1,3}$ gravity to the case of non-zero negative cosmological constant.
